PLOW.

SPECIFICATION forming part of Letters Patent No. 690,033, dated December31, 1901.

Application filed April 30, 1901. Serial No. 58,196. (.ll'o model.)

To all whom zit may concern.-

Be it known that I, THOMAS Rronnonn, a citizen of the United States,residing at San Marcos, in the county of Hays and State of Texas, haveinvented a new and useful Plow, of which the following is aspecification.

The invention relates to improvements in plows.

The object of the present invention is to improve the construction ofplows and to provide a simple, inexpensive, and strong construction foradjustably supportinga rudder-blade adapted to be employed in connectionwith a middle-breaker moldboard.

The invention consists in the construction and novel combination andarrangement of parts, hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a plow constructed inaccordance with this invention. Fig. 2 is a horizontal sectional view onthe line 2 2 of 1. Fig. 8 is a detail perspective view of the adjustablerudder-blade.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a plow-beam, preferably constructed of metal and having itsrear end curved downward, and pivoted to the rear end of the plow-beamis a pair of standards 3, perforated between their ends for thereception of the pivot at and extending upward and downward from therear end of the plowbeam. The standards are spaced apart at their lowerends by a block 5, and the lower arms or portions of the standards areadapted to receive a middlebreaker moldboard, (not shown,) and the upperportions or arms of the standards are arranged at opposite sides of therear portion of the beam and are adapted to clamp the same, being heldin engagement with the beam by means of a transverse bolt 6. The bolt 6,which is provided with a suitable nut, passes through perforations ofthe upper ends of the standards and is adapted to be readily loosened topermit the standards to be readily adjusted to arrange the moldboard inproper position.

The rear end of the plow-beam supports a pair of handles 7, which areprovided at their lower ends with plates 8, secured to the inner facesof the plow-handles 7 and to the side faces of the plow-beam andinterposed between the same and the standards. The plates of theplow-handles are secured to the plow-beam by the pivot L and by atransverse fastening device 9, located in rear of the pivot 4. Theplow-handles are also braced by rods 10, extending forward from theupper portions of the handles and secured to the plow-beam in advance ofthe standards by a transverse fastening device 11. The rear ends of thebracing-rods 10 are bent inward at right angles and are secured to theplowhandles; but the bracing-rods may be attached to the latter in anyother suitable manner.

The plow is guided by an adjustable rudder blade 12, pivoted at itsfront end between a pair of longitudinal supporting-bars 13 andconnected with the plow-handles by a pair of braces 14.. Thelongitudinal bars 13 are pivoted at their front ends to the standardsata point below the rear end of the plow-beam by a transverse fasteningdevice 15, and the pivot 16, which connects the front end of the blade12 to the bars 13, is arranged at a point between the ends thereof andalso passes through the lower ends of the upright braces 14. The rearends of the longitudinal bars 13 are perforated for the reception of abolt 17, which passes through an approximately vertical slot 18 in therear portion of the blade 12 and which is adapted to be adjusted toclamp the blade in the adjusted position of the latter. The blade has alower inclined front edge, and the upright braces 14:, which areprovided at their upper portions with series of perforations 19, aresecured to the plow-handles by bolts 20 or other suitable fasteningdevices, which permit the braces to be adjusted to swing thelongitudinal bars 18 and the blade 12 upward and down ward. The blade isfirmly clamped between the rear portions of the longitudinal bars andmay be readily adjusted to arrange it to suit the plow.

It will be seen that the rudder-blade is capable of ready adjustment,both by the upright braces and by the means for connecting it to thelongitudinal bars, that the latter are pivoted at their front ends inorder to swing the blade bodily upward and downward, and

that the standards may be readily adjusted by loosening the fasteningdevice at their upper ends when it is desired to adjust the plow.

What I claim is 1. The combination of a plow-beam,handles connectedtherewith, standards pivoted between their ends to the plow-beam andadjustably connected with the same, the longitudinal bars extendingrearward from the standards and hinged at their front ends, a blademounted between the longitudinal bars and braces connecting the bladewith the handles, substantially as described.

2. The combination of a plow-beam,handles connected therewith, alongitudinal bar extending rearward beyond the plow-beam and locatedbeneath the plow-handles and hinged at its front end adjacent to thelower ends of 4. The combination with a plow, of a pair of longitudinalbars hinged at their front ends to the plow, a blade arranged betweenthe rear amass portions of the longitudinal bars and pivoted at itsfront end to the said bars, and provided with a slot, a fastening devicearranged in the said slot and connecting the rear portions of the bars,and braces adj ustably connecting the bars with the plow-handles,substantially as described.

5. The combination of a plow-beam having a downwardly-curved rearportion, plow-handles extending upward and rearward from the back of thebeam, longitudinal rods extending from the beam to the plow-handles, thestandards pivoted between their ends to the rear end of the plow-beam,and arranged at opposite sides of the same and provided with a fasteningdevice connecting their upper portions and holding the same inengagement with the beam, the longitudinal bars pivoted to and extendingrearward from the standards, the blade arranged between the longitudinalbars and pivoted at its front end to the same, means for adjustablyconnecting-the blade to the said bars, and braces extending upward fromthe bars and adjustably secured to the plow-handle,substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

THOMAS RICHMOND.
